 * SP Pro will not activate, I am getting this error, thanks for your help –
 * Plugin could not be activated because it triggered a **fatal error**.
 * **Fatal error**: Unparenthesized `a ? b : c ? d : e` is not supported. Use either`(
   a ? b : c) ? d : e` or `a ? b : (c ? d : e)` in **/webroot/r/e/redbar/primary/
   www/wp-content/plugins/slick-popup-pro/libs/includes/admin-pages.php** on line**

 * Hi Kevincollins
 * This error is related to the PHP version and If you are using PHP 8 then most
   likely this is considered as Fatal Error. Our Team is updated the plugin with
   latest PHP version and latest WordPress. It will most likely be available by 
   next week. You can contact us on support, we will help you fix it immediately.
